I started my 3D printer upgrade series with the Quick tool change which is still one of my coolest upgrades. However, it missed something because if you change to a different tool, you always have to place the hot end somewhere. With the swappable hot end it is possible to disconnect the whole hot end like the Ultimaker printers. Another advantage of this, besides being able to disconnect your hot end, is that you can use different hot ends for different materials or nozzle diameters. After I came up with this idea I found a couple of similar approaches but nothing with which the bowden tube itself could be disconnected.

Another cool thing: if you use a laser engraver, you don’t have to add an extra wire or switches to your control board and you can just connect it directly.

Mounting instructions

Parts needed

Depending on which type of holder you choose you need:

What you need in general:


You can use the pdf below with the wiring diagram which I recommend using. You can of course do it differently if that suits your purpose better.

If you press the collar onto the tube, use a bit of sanding paper to make it flat and use a 2mm drill to remove the burr from the inside of the tube. I did not do this at first and the material was blocked at the point where the two tubes meet in the connectors.

Disclaimer and warning

Use this thing at your own risk. It works for me, but you are modifying the hot end of a 3D printer. I cannot be held responsible if anything goes wrong and messes up your print, machine or if your house catches fire. Use common sense and always wear proper protection when using a laser head, grinder, drill etc.

Make sure that every time you print that the connector is tightened! Otherwise it will come loose while printing.

    Superb implementation, someone actually getting up and doing this…
    I’d procrastinated for some time on making a quick release, even trying to find the connectors used on the Snapmaker – Proprietary , to copying the VGA one done on the new CR10 hybrid machine….
    Couldn’t really find any easy ‘quick fit’ though, always came back to the standard ribbon cables and connectors.

    Can’t see an issue with this and the current handling – a High end heater is 60 watts – at 24Volts that’s less than 3Amps – the pins are mostly rated for that and higher…Could always parallel up if you’re really worrried!

    Hope you can get together some form of small scale production on a kit of these – those hybrid connectors are a pain to source ‘cheaply’
    suggest maybe a breakout PCB style device where you don’t have to solder in cables
